artafast fasteners Germany artafast models artafast prices

artafast fasteners are integrally bonded and vulcanized from rubber rings and metal rings. They are sealing rings used to seal threaded and flange connections, consisting of a metal ring and a rubber gasket. The metal ring is treated for rust prevention, and the rubber ring is generally made of oil-resistant nitrile rubber or fluororubber. Combined gaskets are available in metric and imperial sizes, with standards specifying the combination form of metal gaskets and rubber. Combined sealing washers are used for sealing threaded pipe fittings and plugs. They are generally used together with ferrule-type pipe fittings to seal oil ports, mainly for hydraulic valve pipe joint threaded connections.
